SHA-2

SHA-2 (Secure Hash Algorithm 2) — kriptografik algoritmlar oilasi. AQSh Milliy xavfsizlik agentligi (inglizcha: National Security Agency, NSA) tomonidan 2001-yilda ishlab chiqilgan^[1]^[2].

$\operatorname{Ch}(E,F,G) = (E \land F) \oplus (\neg E \land G)$
     $\operatorname{Ma}(A,B,C) = (A \land B) \oplus (A \land C) \oplus (B \land C)$
    **Failed to parse (Unknown function \ggg): {\displaystyle \Sigma_0(A) = (A\!\ggg\!2) \oplus (A\!\ggg\!13) \oplus (A\!\ggg\!22)}**
    **Failed to parse (Unknown function \ggg): {\displaystyle \Sigma_1(E) = (E\!\ggg\!6) \oplus (E\!\ggg\!11) \oplus (E\!\ggg\!25)}**
